Baghouse Filter Advantages and Disadvantages: Weighing …
Reverse-air baghouse setups use a counter airflow to cleanse the dust from the bags. At set intervals, a fan generates a backward airflow, puffing up the bags and causing the trapped dust to drop into a collection hopper. These reverse-air configurations are commonly chosen for more extensive systems with significant dust loads. Advantages:

How Does a Baghouse Work? | Baghouse America
The polluted air will move through a series of filters throughout a dust collector in the baghouse system. The first series of bags that the air passes through works to accumulate the dust particulate. You may typically find this accumulation on the outside of the filter bags. This separation ultimately allows more clean air to pass through the ...

It's the backbone that keeps the filter bags in place and keeps the dirty and clean air separate. Don't overlook the hopper at the bottom. It's not just a bucket; it's designed to gather and channel dust for easy removal, usually pulling it off with a 95-98% success rate. Last but not least, the air inlet.

Maintenance Checklist for a Better Baghouse
The most important item in a baghouse is the filter media because it allows for the accumulation and support of a dust cake. This dust cake is what provides high filtering efficiencies during operation. A periodic inspection of the filter bags/cartridges is mandatory. Inspect the clean air side of the baghouse for leaks, and the bags for tears.
